A four-storey brick apartment building in Mykolaiv city. The corner wall where the blast hit is now covered with a sheet of polyethylene held down by OSB boards. Windows on two floors are boarded up. The plaster is gone. Four years after the damage was done, people are still living inside — behind temporary materials that protect against rain but offer nothing against the cold. This is not Category 1 territory. And yet, it sits in a policy void that the humanitarian shelter system was not designed to address.
This is not an isolated case. Across Mykolaiv, Kharkiv, Zaporizhzhia, Kherson and Donetska oblasts, thousands of buildings — both private houses and multi-apartment blocks — bear damage that goes beyond the scope of what Category 1 humanitarian repair programmes can legally or technically touch. The humanitarian sector has spent four years delivering windows, doors, and roofing panels. That work was necessary. But in doing so, it has quietly created a shadow caseload of structurally damaged properties that nobody is systematically funding to fix.
The Case Donors Need to Hear
When humanitarian donors fund shelter programmes in Ukraine, they are most comfortable with Category 1: a defined scope, standardised costs, verifiable outputs. A broken window is replaced. A damaged roof is sealed. The numbers make sense. The logic is clean. This comfort has driven the sector's enormous Cat. 1 delivery over the past four years — and it has served hundreds of thousands of households well.
But Category 1 funding has an inadvertent side effect. When an assessment team visits a household, classifies it as requiring structural repair, and marks it ineligible for Cat. 1 assistance, that household does not disappear. It joins a register — sometimes a formal one at the hromada level, sometimes an informal list — of families waiting for something that no current programme is equipped to deliver. Every Cat. 1 grant cycle that ran without a parallel Cat. 2 component made that list longer.
The argument for donors is not a humanitarian abstraction. It is a programme logic argument: if you funded Category 1 repairs and did not fund Category 2, you left the hardest cases behind. The people who most needed help — those whose homes sustained the most severe damage — were systematically excluded from the response by the very scope parameters that made the programme tractable to manage.
Category II (Heavy) Repairs — SN301C — is now formally included in the Shelter Cluster Activity Matrix 2026 with a reference cost of USD 12,000 per household. This is the first time Cat. 2 structural repairs appear as a codified, reportable humanitarian activity in Ukraine's cluster framework. The infrastructure for donor engagement now exists. The funding has not followed.
Not Just Private Houses — The Apartment Gap
The Shelter Cluster SOP for Category 1 Repairs (April 2026) is explicit: structural damage to apartments in multi-apartment buildings is beyond humanitarian scope. The SOP is equally clear on why — load-bearing structural failure in a multi-storey building requires engineering design, permitting frameworks, and capital works that go far beyond what humanitarian actors are mandated or resourced to deliver. That logic is sound.
But it leaves a category of damage entirely unaddressed. Apartment buildings with blast-damaged corners, compromised facades, or partially collapsed stairwell structures exist across every frontline oblast. They are not safe to repair with humanitarian Cat. 1 resources. They are too complex for humanitarian Cat. 2 frameworks that only cover private houses. And they are beyond the reach of eVidnovlennia for households where common space damage blocks compensation access. The families inside are in a full policy void.
What this requires is not a humanitarian solution but a coordinated one — NGOs, local authorities, and national reconstruction programmes working together to create a pathway for structural repair of multi-apartment buildings that sits between humanitarian response and capital reconstruction. That pathway does not exist today. The apartment building in the photograph above is evidence of what that absence looks like in practice.
Rural Communities: The Land That Holds People in Place
In the villages of Mykolaiv, Kherson, and Kharkiv oblasts, there is a dimension to the housing crisis that does not fit easily into humanitarian frameworks built around mobility and displacement. The assumption embedded in most shelter programming is that people who cannot live in their damaged homes will move — to collective sites, to relatives, to cities. In rural Ukraine, that assumption fails.
For a family in a village in Mykolaiv Oblast, the house is not a housing unit. It is the physical anchor of an agricultural livelihood — a kitchen garden, a livestock pen, a fruit orchard, a hectare of arable land that has fed that family for generations. When the house is damaged, they do not leave. They cannot leave. The land is there. The animals are there. The harvest is there. They cover the hole in the roof with whatever they can find and they stay.
This is not obstinacy. It is rational behaviour in a context where urban options are inaccessible. Rental markets in Mykolaiv city are expensive and competitive. Collective sites are designed for short-term accommodation, not agricultural families who need to be outdoors at five in the morning. A village grandmother with chickens and a vegetable patch cannot live in a dormitory in Odesa and maintain the productive system that is her only income.
The consequence is that rural households with structural damage — damage that Category 1 cannot touch — are living in partially collapsed structures, in outbuildings, in neighbours' homes, waiting. Not waiting to leave. Waiting to be able to come back to the home that stands on the only piece of land they have.
The humanitarian case for Category 2 in rural settings is therefore also a food security case, a livelihoods case, and a durable solutions case. A structural repair that enables a farming family to return to their land is not just shelter assistance — it is the intervention that prevents prolonged dependence on humanitarian assistance across multiple sectors simultaneously. The cost-effectiveness argument writes itself.
What Heavy Repairs Actually Look Like
For those unfamiliar with Category 2 structural damage at the household level, the photographs here tell the story more directly than any definition. What distinguishes Cat. 2 from Cat. 1 is not the size of the hole — it is what the hole has done to the structure around it. A wall that has lost its load-bearing capacity does not behave like a wall with a broken window. It creates a cascade: the roof sags, the ceiling drops, the floor plates shift. A contractor who arrives to replace windows is not equipped — legally, technically, or financially — to address what is underneath.
A Category 2 intervention requires a proper engineering assessment — not just a visual inspection — followed by a structural calculation, a project-specific Bill of Quantities, and a contractor with the capacity to actually execute works safely. The difference in process is as significant as the difference in cost.
One model gaining operational traction is the Framework Agreement approach: pre-qualifying a contractor to deliver both the technical design and the works under a single pre-arranged agreement. This collapses the timeline between assessment and works commencement — critical for families who have already been waiting three or four years in damaged structures for something to happen.
Longer grant timelines. Category 2 projects cannot be executed in six months. Engineering assessment, design, procurement, and works require twelve to eighteen months minimum.
Higher unit costs. The $12,000 reference cost is an average. Complex rural structural repairs — particularly in areas with limited contractor access — will exceed this. Donors should expect and plan for this.
Engineering capacity. Partners implementing Cat. 2 must have qualified engineers on staff or under contract. The humanitarian sector's existing capacity for this is limited and will need to grow.
Rural access budgets. Reaching dispersed rural households in frontline oblasts carries real logistical costs. Access and transport budgets need to reflect this explicitly.
The Moment to Act
Ukraine's shelter response is at a strategic inflection point. Category 1 needs — still real, still present — are declining in volume compared to the peaks of 2022 and 2023. What is replacing them in the caseload is structurally harder, more expensive, and more complex. The sector's tools and the donors' comfort zones have not yet caught up with that shift.
The families in these photographs — in a Mykolaiv city apartment building and a village house in Mykolaiv Oblast — represent the leading edge of what the Ukraine shelter response has not yet reached. For the apartment residents, there is currently no mechanism. For the rural family on their land, the mechanism exists in theory and is absent in practice.
Category 2 is not a niche activity for a small caseload. It is the unfinished business of four years of humanitarian shelter response — the cases that were assessed, documented, and set aside because the funding envelope was not wide enough to include them. The Shelter Cluster has now formalised the activity. The policy framework exists. What is needed is the donor decision to fund it at scale — and the willingness to accept that rebuilding what war destroyed, structurally and permanently, costs more than patching what it damaged.
